format -eselect the disc which you are trying to install onto, if you are told that the disc doesnt not contain a disk label, would you like to write a lablel, say yes & specify the type as SMI Label, If youre not asked about the label & presented with a menu, goto the partition section, choose label, specify the type as SMI.
quit & reboot & all should be well
